I'm used to seeing the other side of it, Australia fought against North Vietnam as you would know.
Indeed, though I only learned of it from watching The Battle of Long Tan, seeing ANZACs fighting alongside the GIs. It's interesting to see how they're glorifying their victory, even if it means disgracing their former rivals. To be realistic though, a lot of the history that I've read so far did seem to show how poorly the French fought in the Indochina War.
The Brits, including the now disarmed Japanese were there fighting against the Viet Minh since just after WW2, and they had far better success then, just before the French came back. To think that the entire Vietnam War could've scarcely been avoided, if the French generals had stopped munching on onions, and had directed the war properly.
